Minutes
Attending: Brad Smith, Alexey Radovinsky, Elton Smith, Glenn Young, Eugene Chudakov, George Biallas, Tim Whitlatch, Jonathan Creel
- Brad and Alexey were given tours of the experimental Hall D and the coil test in the Test Lab
- Discussions began with presentations by Alexey (magnetic and mechanical design) and Brad (conductor choices)
- Magnetic and mechanical design (Alexey)
- Used ANSYS 2D and Vector Fields 3D modeling
- Fringe fields 6m downstream is calculated at 230-250 G, exceeding the specification. No cladding was included to this point, but will be added and fields checked
- Three subcoils used to produce the field profile
- Calculated axial Lorenz forces on coils was 1.4 MN.
Action Items
- Complete interface drawings with sign off. (Tim)
- Also make available drawings of filler rings.
- Include estimate of Helium level
- Provide parameters of refrigerator and cryogenic system (Johnathan)
- Provide drawings of service cryo cans (both D and C types) (George)
- Add cladding to model and repeat magnetic calculations to check fringe fields (Alexey)
- Send (draft) presentation to everyone (Alexey and Brad)
- Consider options for inserting coil from upstream end. (JLab)
- Preference is to have the chimney upstream (to minimize saturation downstream and have lower fields at current leads), but will weigh alternatives
- Provide guidance on location following evaluation
- Provide estimate weight of coil (Brad)
- Provide table of lengths of SSC cable, so that splicing options can be studied (Elton)
- Get name of company that is extruding copper channel for conductor (Elton/Glenn)
- Provide information regarding the nitronic rods (non-magnetic stainless) as an option for tensioning supports (Tim)
- Specify guidelines (requirements) for burnout-proof leads (George?)
